WorldView-2卫星矿山遥感监测:以西藏罗布莎地区为例

Remote Sensing Monitoring on Mine of WorldView-2 Satellite:A Case Study of the Luobusa Area,Tibet

矿山遥感监测是近年来国土资源部门管理矿产资源开发、整顿和规范矿业秩序的一项重要的矿情调查工作。西藏罗布莎铬铁矿区是我国铬铁矿的主要产区,随着国民经济的快速发展,对铬铁矿石的开采力度和强度在逐年增大。为了更好地促进矿产经济及环境的可持续发展,选用World View-2遥感数据,首次深入分析了罗布莎矿山开发过程中不同地物遥感影像特征,建立了各类矿山地物的高空间分辨率遥感解译标志,通过遥感解译与野外查证工作,基本查明了研究区矿山开发状况和矿山地质生态环境现状,并对矿区开发现状与矿山环境进行了统计和分析,基于遥感矿山监测,给出了合理的矿山环境恢复建议。结果表明:World View-2作为高分辨率遥感影像,空间分辨率高,包含全色和8个多光谱波段,信息量丰富,解译精度高,在矿山遥感监测乃至更广范围的动态监测中应用可以取得很好的效果。

Remote sensing monitoring of mine is an important survey work for exploitation of mineral resources,reorganization and standardization the order of mining industry by Ministry of Land and Resources in recent years. Chromitites mining area in Luobusa is the main chromitites production mine region in China. The exploitation intensity of mineral resources increases year by year due to the rapid development of national economy. In order to promote the sustainable development of the mining economy and environment,this article selects the World View-2 remote sensing data and profoundly analyzes remote sensing image characteristic of different surface features in the mine development process. Through field verification,we take advantage of World View-2 high spatial resolution remotely sensed data to establish the remote sensing interpretation keys of mine features so as to clarify development situation and ecological environment of this mineral area,and then conduct statistics and analysis of mining conditions and environment. Based on remote sensing monitoring of mine,reasonable suggestions about mine environmental recovery are given. Results show that World View-2 are with rich information and high precision of interpretation due to its high spatial resolution,panchromatic and eight multi-spectral bands,can obtain good effect in the remote sensing monitoring.
